Isringhausen hasn’t told the Mets whether or not he will accept the assignment. He originally said if he did not make the club he would retire or go home and see if another opportunity arises elsewhere.

“I think it was durability, No. 1, in the sense of being able to pitch back-to-back and frequently over periods of days,” Mets general manager Sandy Alderson said. “And the second was just long-term durability and how he’ll hold up. Right now it’s being able to pitch routinely, consistently.”

Alderson said he would let Isringhausen go if in the next week another club says it has a spot for him on its roster. He is not guaranteed to make the Mets’ roster after his time in extended spring training.

“There’s always going to be injury risk with Jason, but the next two weeks will tell us a little more about his velocity, a little more how he bounces back at the end of the day and a little bit more about our own situation in New York with the bullpen,” Alderson said.ut.”

Fellow reliever Manny Acosta was designated for assignment on Tuesday.
